          """
          The fromGeoCoordinateString operation is performed on a geometry
          service resource. The operation converts an array of well-known
          strings into xy-coordinates based on the conversion type and
          spatial reference supplied by the user. An optional conversion mode
          parameter is available for some conversion types.
  
          Inputs:
           sr - The well-known ID of the spatial reference or a spatial
            reference json object.
           strings - An array of strings formatted as specified by
            conversionType.
            Syntax: [<string1>,...,<stringN>]
            Example: ["01N AA 66021 00000","11S NT 00000 62155",
                      "31U BT 94071 65288"]
           conversionType - The conversion type of the input strings.
            Valid conversion types are:
             MGRS - Military Grid Reference System
             USNG - United States National Grid
             UTM - Universal Transverse Mercator
             GeoRef - World Geographic Reference System
             GARS - Global Area Reference System
             DMS - Degree Minute Second
             DDM - Degree Decimal Minute
             DD - Decimal Degree
           conversionMode - Conversion options for MGRS, UTM and GARS
            conversion types.
            Conversion options for MGRS and UTM conversion types.
            Valid conversion modes for MGRS are:
             mgrsDefault - Default. Uses the spheroid from the given spatial
              reference.
             mgrsNewStyle - Treats all spheroids as new, like WGS 1984. The
              180 degree longitude falls into Zone 60.
             mgrsOldStyle - Treats all spheroids as old, like Bessel 1841.
              The 180 degree longitude falls into Zone 60.
             mgrsNewWith180InZone01 - Same as mgrsNewStyle except the 180
              degree longitude falls into Zone 01.
             mgrsOldWith180InZone01 - Same as mgrsOldStyle except the 180
              degree longitude falls into Zone 01.
            Valid conversion modes for UTM are:
             utmDefault - Default. No options.
             utmNorthSouth - Uses north/south latitude indicators instead of
              zone numbers. Non-standard. Default is recommended
